Methodologies

DISCIPLINED AGILE  DELIVERY (DAD)

SCALED AGILE FRAMEWORK (SAFE)

SOFTWARE DEVEOLMENT (SCRUM)

Definitions

DAD practices decision framework which is used for enabling simplified procedure for decisions around both solutions delivery i.e. the iterative and the incremental.

SAFE is designed by the Scaled Agile, and is a software development for agile framework. SAFE comprises of knowledge base with integrated patterns which intend to enterprise –scale the Lean-Agile development. 

SCRUM is defined as both the incremental and the iterative software development for agile framework by the management for the development of product.

Roles

DAD comprises of two roles:

Ø Primary roles.

   These are those roles which occur without considering scale level. (Ambler, 2012) These include:

· Team lead: 

Team lead also led as an agile coach whose responsibility is to optimize processes, ensures high availability of resources free from obstacles and facilitates communication.

· Product owner:

Is the only individual, speaks as “one voice of the customer”. He/she solely represents the requirement of stakeholder’s community to team for agile delivery.

· Architecture owner:

Is responsible for facilitating evaluation and creation of complete solution design. He/she also architect’s the team decisions.

· Stakeholder:

Is the one gets impacted with the solution’s outcome. Stakeholder is directly affected by the development and deployment of software project.

· Team member:

His role is to focus as per the actual requirement by stakeholders. Programming, planning, analyzing, testing, estimating, designing and lots of other activities as required in a project will be performed by team members.

Ø Secondary Roles

These are those roles which got introduced for addressing scaling issues. These include:   

· Integrator:

Is responsible to build complete system from the integrator’s different subsystems.

Ø Specialist:

As per project needs sometime Specialists are required.

Ø Independent Tester:

Few DAD team gets support from Independent test team which work parallel for validation of work.

Ø Domain expert:

Usually required in complex domains.

Ø Technical expert:

At the time of difficult issues a technical expert is required.

Following are the SAFE roles which includes:

Ø To manage their work.

Ø To work with the goal of continuous improvement.

Ø To estimate size and complexity of work.

Ø Responsible to build with continuous improvement in the quality of the deliverables.

Ø They work to accomplish program increment (PI) or an iteration timebox.

Ø They determine technical design within their concerned area, as per the architectural guidelines. (Leffingwell, 2007)

SCRUM Framework comprises of following three roles. It includes:

Ø Product Owner

· Represents the voice

of the customer and stakeholders.  

· An important aspect is to ensure team members work to enhance deliverable values of the business.

· Writes customer-oriented items, include them in product backlog, also they prioritize these as per the vitality and dependency.

· Bridges gap between team and stakeholders.

Ø Development Team

Development team role is to ensure the delivery of product’s potentially shippable increments (PSIs) at each Sprint end.

Ø Scrum Master

· Accountable to remove hindrance in the team’s path to deliver highest level deliverables and the product goals.

· Acts as Team’s Protector. He/she stands between distracting influential and team.

· Make sure that team is following Scrum framework.

· Facilitates about team events and educating Scrum principles to the stakeholders.

· Tries to promote self-organization within the team. (Henry, 2003)

Processes

DAD provides light-weight guidance, which assists company for streamlining processes of information technology with context-sensitive form. DAD includes following processes:

Ø Delivery process:

It promotes working as a whole, start –to-finish and complete lifecycle of solution delivery (e.g. scrum-based, continuous delivery, Kanban-based and also exploratory lifecycle). Delivery process includes following concepts of inception, construction, transition and production.

For supporting light-weight approach in tailoring process, framework of DA (Disciplined Agile) framework uses approach of goal-driven. Its main goal is to help an individual with process-related decisions which they require to scale agile also to tailor strategies that can be created to address the current situation.

Ø Information Technology (IT) Process:

2.0 DA framework has been released in order to support all sort of activities related to IT. Below overviews process blades of DA 2.0.

DA software delivery team follows a lifecycle which is context-driven. It contains Agile, basic, lean, advanced, exploratory, continuous delivery and also program management. Disciplined DevOps streamlines both IT delivery and the operations which contains operations, release management, data management and support. At last, DA IT, is the one in which everyone of IT eco-system is involved. They all works in very collaborative, evolutionary and learning-oriented manner.

Also, DA IT contains management of people, product, portfolio, architecture of enterprise; reuse engineering, governance of IT and finally continuous improvement.

Following include the SAFE processes:

Ø Agile Transformation:

First process which comprises Transformation of Scaled Agile with RAGE, SAFE and Transformation of Pilot Agile.

Ø Development of Agile Hardware:

This process contains Training and Piloting of Agile Hardware

Ø Phases of Agile Implementation:

This includes Assessment of Agile Readiness, Strategy Planning of Agile Foundation, Coaching, Training and Mentoring of Agile, Maintenance of Agile and finally Changing Management Services.

Ø Training of Agile:

This process comprises of all Public, Online and Private Training.

Ø Case Studies of Agile Transformation

SCRUM process assists work items which plan and track work, review the code, takes feedback and finally test the code. A SCRUM process can be explained in below five phases:

Ø Initiate:

Initiate consists of processes which help in creating project vision, identifying Scrum Master and stakeholder, structuring Scrum Team, originating Epics, developing the product Backlog as per the priority and regulating release planning.

Ø Plan and estimate: This phase consists of processes which help in generating, approving, estimating and committing user’s stories. It helps in estimating and creating tasks and also creates sprint backlog.

Ø Implement:

This phase consists of processes which help in generating deliverables, organizing daily meeting and also grooms the product backlog as per the priority. ( Leybourn, 2013)

Ø Review and Retrospect:

This phase consists of processes which help in assembling Scrum within the Scrums; retrospect the sprint and finally signifying and validating sprint.

Ø Release.

This phase consists of processes which help in shipping deliverables and finally retrospect project.

Complexity

It is viewed usually as being very complex and the complexity of technical that the professionals IT may experience contain:

Ø Platforms for new technology

Ø Contains various technology platforms

Ø Legacy of the data

Ø Legacy systems

Ø Solutions for the embedded system.

Ø Solutions for the Commercial off-the-shelf

Its complexity exists mostly emotionally on question whether the approaches of the scaling agile are adequate or not sufficient. This is very complex for the unknown probe-sense-response for practicing which is emergent. Its demands learning, probes fail-2-safe, failures and courage.

Its look for the complexity at the modification of the cost. It believes the code complexity. It is also relative to experience and knowledge of the individual who appropriate the object force. They could understand easily the complexity of experience and knowledgeable that is equal in all the members of the team members. (Roman, 2010).

Usage

This is used mostly for cracking the solution for the stakeholders.

This is used for creating the whole system from the subsystem.

Agile development used SAFE and scales the lean in any bigger software organization.

This is utilized for giving assistant to the team and executives with consulting coaching, training and services.

This is used for transforming the management of project across all the industry, like and business in general. For instance, one is capable enough for responding accurately and quickly reacts to the inevitable modifications.

This is used by various universities for delivering projects that are valued to the customers.

For ship deployment used by the militaries.

Tools

For tools this framework is orthogonal (principles, techniques and practices that captured with framework that are independent for particular tools). Such tools contains rational method composer, method park stages, enterprise transformation advisor, Blueprint and Microsoft TFS. ( Heusser, 2015)

Tools that are utilized for supporting SAFE depend on levels. The tools contain Kanban board, global roadmap, scrum board and Plutora. ( Philippe, 2014)

Tools which support SCRUM contains agile buddy, agile soup, agile bench, agile agenda, version one, sprint ground, pivotal tracker, agilo for the SCRUM and ActiveCollab.

Spreadsheet – This is used for building and maintaining the artifacts used such as Sprint Backlog

Open-source and proprietary software – these are the SCRUM packages. ( Brown, 2013)
